10 Claims.

This invention relates to apparatus for use in applying pressure to shoebottoms and more particularly to pad boxes for use in attaching soles tothe bottoms of shoes by cement although it will be understood that theinvention is not thus limited in its application.

It is an object of the present invention to provide an improved pad boxof simplified construction suitable for use with a wide range of sizesof juvenile shoes and suitable for operation upon such shoes havingeither a spring heel or a fiat heel.

In accordance with a feature of the invention the pad box employs a padof yielding material such as rubber the central portion of which isapertured to receive inserts of like material which operate on the shankand heel portions of the shoe. Provision is made for imparting relativeheightwise adjustments to the inserts in the shank and heel portions toaccommodate and properly distribute the pressure to the shank and. heelportions of shoes of a wide range of sizes. The insert under the heelportion of the shoe is adjustable vertically to accommodate the pad toshoes having spring heels or fiat heels. Further to accommodatedifferent sizes and styles of juvenile shoes the forepart portion of thepad is adjustable about an axis extending transversely of a shoe on thepad, the axis being located adjacent to the forward portion of theaperture in which the inserts are located.

The above and other objects of the invention including various detailsof construction and novel combinations of parts will now be described byreference to the drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a vertical longitudinal section through one form of pad box inwhich the invention is embodied, illustrating the positions of the partswhen a large size juvenile shoe with a spring heel is being operatedupon, the section being taken along the line 1-1 of Fig. 4 r

Fig. 2 is a fragmentary sectional view of a portion of the structureshown in Fig. 1, illustrating the positions of the parts When operatingupon a shoe having a fiat heel;

Fig. 3 is a plan view of the pad box with a portion of the cover removedto illustrate the arrangement of the inserts in the rubber pad; and

Fig. 4 is a plan view of the pad box with the pad removed to illustratethe supporting plates therefor.

The pad box includes a supporting base I upon which is pivotally carrieda supporting plate [2 for the forepart portion of a pad It, supportingplates l5, It for inserts 20, 2|, 22, adapted to underlie the shankportion of a shoe on the pad, a supporting plate 23 for an insert 24,arranged to underlie the heel portion of theshoe and a fixed supportingplate 2t for the heel end portion of the pad it. The plate 26 whichconstitutes a fixed portion of the base ll) has forwardly extendingsupporting portions 28 (Fig. 4) for supporting those portions of the pad[4 which extend alongside the aforementioned inserts. As shown in Fig.3, the inserts 20, 2|, 22, 24 are located in a vertically extendingaperture in the pad Hi and are surrounded on their sides by the pad IQ.

The supporting plate I2 is provided with a vertical wall 35! whichengages the sides of the forepart portion of the pad [4 and is providedwith ears 32 (Fig. 4) which are apertured at 33 to receive pins 34carried by side walls 35 of the base it extending upwardly from thepad-supporting portions 28. As shown in Figs. 1 and 4, the pins 34 aresmaller than the apertures 33 and merely provide means for holding thesupporting plate H. in assembled relation with the base H! but are notintended to sustain the force exerted on the plate during a pressureapplying operation. For thus supporting the rearward portion of theplate 12 the ears 32 are formed on their undersides with curved bearingportions 38 (Fig. 1) which rest on correspondingly curved portions 40 ofupwardly extending lugs 42 carried by the base It]. The center ofcurvature of these portions is coincident or nearly so with the pins 34.Also jour-- naled in the base at its too end is a shaft 44 carry-'- inga pair of five-sided cams it for sustaining;

the pressure on the supporting plate I 2 forward- 1y of the pins 34. Theshaft 44 is provided withl a handle t8 by which it can be rotated toadjust.-

the positions of the cams t6 and consequently tovary the amount oftipping of the plate l2 about the center of curvature of the bearingsurfaces 38 in accordance with the size or toe spring of the shoe beingoperated upon.

The supporting plate 16 by which the shank supporting inserts 29 and 2|and the adjacent portions of the pad M are carried is journaled on ashaft 50 carried by the base and the supporting plate it for the insert22, and the adjacent portion of the insert 24 is connected to therearward end of the plate l6 by a pin 52. The rearward end of the plate[8 rests on a flat bearing surface of a bracket 54 carried by the platel0. Near its rearward end the plate I6 is provided with a bearingsurface 56 arranged for contact with a 3 five-sided cam 58 secured to ashaft 60 journaled in the base l and provided at its outer end with ahandle 62 by which the shaft and the cam 58 may be rotated to presentany one of the five sides of the cam to the bearing surface 55. It willbe apparent that rotation of the cam 58 will adjust the inclination ofthe plate I5 by tipp it about the axis of the shaft 50 thus to vary theheightwise position of the inserts 20, 2| supported by the plate, theinsert 2| being adjusted to a greater extent than the insert 20. Thesupporting plate |8 being pivoted to the plate It moves with the platel6 during its adjustment, the

lower or rearward end of the plate |8 sliding alon 22 as well as theforward portion of the insert 24 V which is arranged to underlie theheel portion of the shoe being operated upon.

The plate 23 by which the insert 21 is principally carried is j-ournaledfor tipping movement about the axis of a shaft 64 and the forwardportion of the supporting plate 23 rests on a cam 6'6 secured to a shaft68 journaled in the base of the apparatus and provided at its outer endwith a handle it by which the position of the cam 56 may be adjusted. Asillustrated herein this cam is intended to assume either one of only twopositions as shown in Figs. 1 and 2 although it will be understood thatby a proper choice of cams the plate 23 might be moved into any one ofmore than two positions. By moving the plate into the position shown inFig. 2 the insert 24 is lifted to accommodate a flat or substantiallyflat heel shoe.

The block l4 and the inserts 20, 2|, 22 and 24 are provided with a cover12 of leather or other suitable material engageable with the bottom ofthe shoe during the pressure applying operation. A U-shaped plate 74 issecured to the wall 36 of the forepart supporting plate |2 to overliethe marginal portions of the cover 12 retaining it in place. Plates 16secured to the side walls 35 overlie the marginal portions of the cover72 and plates 18 overlie the heel end of the cover so that the cover isproperly held in place throughout its length.

With the parts positioned as shown in Fig. l, the inserts 20, 2| and 22are in their uppermost positions insuring the proper distribution ofpressure along the shank portion of a large size juvenile shot having aspring heel. The heel supporting plate 23 is in its lowermost positionbecause the shoe is equipped with a spring heel. If now a smaller shoeis to be operated upon the cam 55% may be turned to lower the plates l6and i8 in accordance with the size of the shoe to change the contour ofthe pad in the shank portion by lowering the inserts as required. Whenoperating upon a fiat heel shoe the insert 24 should beelevated to closethe space between the pad and the heel end of the shoe which wouldotherwise exist due to the flat contour of the shoe bottom. This insertis raised by turning the cam 66 into the position shown in Fig. 2 atwhich time the inserts 20, 2| .and'2'2 are low-. ered as indicated bythe position of the supporting plate It. Further adjustments of theapparatus to accommodated varying conditions are accomplished byrotation of the shaft 44 and with it the cams 46 to vary the angularposition of the forepart pad-supporting plate l2.

From the-above it will be seen that a pad box of simple construction hasbeen provided in which it is possible to operate onawide range of sizesof juvenile shoes having various bottom contours, and. a pad box of thetype illustrated herein is capable of operating upon shoes from verysmall infant sizes such as size 3 or smaller up to childrens size 12 orlarger without the necessity of utilizing auxiliary pad members whichmust be added or removed to accommodate different sizes or types ofshoes.
